If I had the chance to go back in time, I would repeat school again. I was easily influenced by doing negative things in school which provided me a lack of education. One day I've realized how much it was affected my life so did a complete turn for the better :)

It would be nice to repeat school again and have more confidence in picking up the girl I had a crush on, and develop myself into a much better person and education.

How about you guys? What would you change if you could go back in time?

I couldn't imagine changing anything in the past. I'd be to frightened by the results of my screwing around in the past. Even if their were no consequences, I don't think I'd be happy with the results of changing the past.
So, I'd change nothing.
